title: Macrophage activation syndrome as initial presentation of systemic lupus erythematosus.
abstract: Macrophage activation syndrome (MAS) is known to be a severe and potentially life-threatening complication of rheumatic disorder, especially systemic juvenille rheumatoid arthritis. It is very rare for MAS to be an initial presentation of systemic lupus erythematosus (SLE). Here, we report a 14-year-old girl in whom MAS developed as an initial presentation of SLE. With early diagnosis and administration of cyclosporine A, she had a fair outcome. Further testing showed positive anti-dsDNA about 8 months later.
